Spot Forecast for Knob II RX...Marin County Fire Department
National Weather Service San Francisco CA
706 AM PDT Tue Jul 1 2025

Forecast is based on ignition time of 0600 PDT on July 01.
If conditions become unrepresentative, contact the National Weather
Service.

.DISCUSSION...The marine layer is expected to hover around 1500ft
over the next day or so, which has allowed stratus to intrude inland
and around the burn site this morning. Clouds should mix out by mid
to late morning leading to clear skies for the afternoon. Depending
on this timing, we could see temperatures on the warmer end, in the
80s vs the 70s, and minRH values on the lower end perhaps near 35
to 40 percent if clouds erode quickly. If they take a touch longer
we could see temperatures closer to the upper 70s to low 80s and
minRH values closer to 45 to 50 percent. In addition to that, we
should see a brief uptick in winds during the afternoon to early
evening hours where gusts up to 20 mph are possible. The marine
layer should bring a blanket of clouds again tonight and lead to
very good to near excellent recovery.
